After studying several tutorials on creating the Tyndall effect, I’m planning to fine-tune the lighting to make the light beams more visually pronounced.
The final adjusted result is roughly as shown in the image. I experimented with lighting of different intensities: Option 1 (P1) uses very strong light, which can focus attention on the mermaid like a spotlight, but it is too intense to blend well with the environment. Therefore, I ultimately chose Option 2 (P2) as the final version.
